Types

type UniqueStrings

type UniqueStrings struct {
	// contains filtered or unexported fields
}

UniqueStrings is a collection of distinct strings.

func NewUniqueStrings

func NewUniqueStrings() *UniqueStrings

NewUniqueStrings return a new empty UniqueStrings collection.

func (*UniqueStrings) Add

func (col *UniqueStrings) Add(s string) int

Add method adds the given string to the collection, if not already present. New strings are added at the end of the collection. Returns the item's position.

func (*UniqueStrings) AddSlice

func (col *UniqueStrings) AddSlice(astr []string)

AddSlice adds all element of the slice to the collection.

func (*UniqueStrings) Contains

func (col *UniqueStrings) Contains(s string) bool

Contains returns whether the given item is in the collection.

func (*UniqueStrings) Index

func (col *UniqueStrings) Index(s string) (int, bool)

Index returns the position of the given element in the collection.

func (*UniqueStrings) Len

func (col *UniqueStrings) Len() int

Len returns the number of elements of the collection.

func (*UniqueStrings) Sort

func (col *UniqueStrings) Sort()

Sort order the collection of strings.

func (*UniqueStrings) ToSlice

func (col *UniqueStrings) ToSlice() []string

ToSlice returns the collection items as a slice.

func (*UniqueStrings) Value

func (col *UniqueStrings) Value(i int) string

Value returns the element of the given position in the collection. if i<0 or i>=col.Len(), panic with "index out of range" runtime error.
